After Xerxes decided to go to war against his upcoming opponent, 'Fergie' told the media: "I honestly don't understand the way he sets his team up at times, they lack shape and don't always attack with purpose.

"They have good players but seem to struggle as a team."

The comments could quite easily be a real-life withering assessment of Moyes' current failings in the Old Trafford hotseat.

The champions have struggled to adapt under the former Toffees boss, and they are currently 15 points behind Premier League leaders Chelsea.

Moyes' men are also 11 points off Liverpool in fourth place, and face an uphill task to rescue their Champions League hopes following a miserable 2-0 defeat to Olympiakos on Tuesday evening.
